Journal Article 2023 07 01 Housing is one of the essential needs of human beings; therefore, efficient planning and policy-making to provide it for all of society are very necessary. The housing policy-making after the iran's revolution has had major differences, and various orientations. According to housing experts, these efforts have been sometimes successful and generally failed and have had a significant effect on the supply and demand of housing in the country. Therefore, the main issue is the ineffectiveness of some of these policies in providing housing during the revolution until now. The purpose of the essay was to do a comparative study of the land and housing policies in the iran's development plans and to determine their effectiveness according to the statistical data on housing in certain period[1]s after the revolution. A comparative study with a mixed (quantitative and qualitative) approach has been considered to achieve this purpose. In order to collect data, non-reactive measures and documentary methods have been used. For analysis, the concepts extracted from these texts, have been coded, classified, and organized under categories and subcategories. Then, they have been qualitatively compared over five-year periods. In the next step, a comparative study between quantitative housing data was done in the same periods. Finally, using the TOPSIS model, these plans have been ranked based on efficiency. The results show that the fifth economic, social and cultural development plan has the most efficient policies. On the contrary, the sixth plan is considered the most ineffective development plan since the iran's revolution.
